1.Recent pharmacological developments in the treatment of perennial and persistent allergic rhinitis.
Klimek L1, Mullol J2, Hellings P3, Gevaert P4, Mösges R5, Fokkens W6. Expert Opin Pharmacother. 2016 Apr;17(5):657-69. doi: 10.1517/14656566.2016.1145661. Epub 2016 Mar 3.
INTRODUCTION: Allergic rhinitis (AR) has a major negative impact on patients' quality of life (QoL) and carries a high socio economic burden. This is particularly the case for patients who experience symptoms for extended periods of time (i.e. those with perennial (PAR) or persistent AR (PER), depending on the classification system used). This review covers available pharmacological advances and recent developments in the treatment of PAR or PER.
2.Simultaneous determination of Fluticasone propionate and Azelastine hydrochloride in the presence of pharmaceutical dosage form additives.
Merey HA1, El-Mosallamy SS2, Hassan NY1, El-Zeany BA1. Spectrochim Acta A Mol Biomol Spectrosc. 2016 May 5;160:50-7. doi: 10.1016/j.saa.2016.02.010. Epub 2016 Feb 18.
Fluticasone propionate (FLU) and Azelastine hydrochloride (AZE) are co-formulated with phenylethyl alcohol (PEA) and Benzalkonium chloride (BENZ) (as preservatives) in pharmaceutical dosage form for treatment of seasonal allergies. Different spectrophotometric methods were used for the simultaneous determination of cited drugs in the dosage form. Direct spectrophotometric method was used for determining of AZE, while Derivative of double divisor of ratio spectra (DD-RS), Ratio subtraction coupled with ratio difference method (RS-RD) and Mean centering of the ratio spectra (MCR) are used for the determination of FLU. The linearity of the proposed methods was investigated in the range of 5.00-40.00 and 5.00-80.00μg/mL for FLU and AZE, respectively. The specificity of the developed methods was investigated by analyzing laboratory prepared mixtures containing different ratios of cited drugs in addition to PEA and their pharmaceutical dosage form.
3.Efficacy of topical application of 0.03% tacrolimus eye ointment in the management of allergic conjunctivitis.
Hazarika AK1, Singh PK1. J Nat Sci Biol Med. 2015 Aug;6(Suppl 1):S10-2. doi: 10.4103/0976-9668.166051.
BACKGROUND: Allergic conjunctivitis is commonly observed eye diseases in Sikkim, India due to the abundance of seasonal pollens, environmental pollutants, and house dust. We evaluated the efficacy of topical 0.03% tacrolimus eye ointment in the management of simple allergic conjunctivitis.
